Purpose Rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisone administered every 3 weeks (R-CHOP-21) is the standard care for diffuse large B-cell lymphoma (DLBCL). It is unknown whether the dose-dense R-CHOP (R-CHOP-14) could improve the outcome of the disease in Asian population. Materials and Methods Newly diagnosed DLBCL patients were centrally, randomly assigned (1:1) to receive R-CHOP- 14 or R-CHOP-21. R-CHOP-14 was administered every 2 weeks, and R-CHOP-21 was administered every 3 weeks. Primary end point was disease-free survival (DFS). Secondary end points included overall survival (OS), progression-free survival (PFS), response rate and toxicities. Results Seven hundred and two patients were randomly assigned to receive R-CHOP-14 (n=349) or R-CHOP-21 (n=353). With a median follow-up of 45.6 months, the two groups did not differ significantly in 3-year DFS (79.6% for R-CHOP-14 vs. 83.2% for R-CHOP-21, p=0.311), 3-year OS (77.5% for R-CHOP-14 vs. 77.6% for R-CHOP-21, p=0.903), or 3-year PFS (63.2% for R-CHOP-14 vs. 66.1% for R-CHOP-21, p=0.447). Patients with an International Prognostic Index (IPI) score ! 2 had a poorer prognosis compared to those with an IPI score < 2. Grade 3/4 hematologic and non-hematologic toxicities were manageable and similar between R-CHOP-14 and R-CHOP-21. Conclusion R-CHOP-14 did not improve the outcome of DLBCL compared to R-CHOP-21 in Asian population. With manageable and similar toxicities, both of the two regimens were suitable for Asian DLBCL patients. For high-risk patients with IPI ! 2, new combination regimens based on R-CHOP deserve further investigation to improve efficacy.

In the industrial production, water exists inevitably into feed stocks in the form of impurity, and it can produce a negative effect in the hydrogenation reaction due to the preferential adsorption of water on active sites. Here, the surfactants (polyvinylpyrrolidone, poloxamer, polyethylene glycol and hexadecyl trimethyl ammonium bromide) are used to improve physicochemical property of Cu/SiO2 catalysts, so that Cu/SiO2 catalysts had a good hydrogenation performance at condition containing water. The appropriate addition amount of surfactants in the catalyst preparation process effectively hindered the agglomeration of copper species by steric configuration and repulsion effect between Cu2+ and positive ionizable, which brought about high copper dispersion and small particle size. Meanwhile, the decomposition of surfactants produced many pores during calcination, resulting in the increased of specific surface area and average pore diameter. These advantages provided more chances for reactants to touch active sites due to spatial restriction and the increase of the number of active sites, so that the negative effects of water can be counteracted. The conversion of Cu/SiO2 catalysts, that the surfactants was added in the catalyst preparation process, increased 60% to 200% at reaction condition containing water.

<P>A high refractive index (RI) and transparent encapsulant material is in great demand for light emitting diode (LED) packaging to lower the RI contrasts between a LED chip and an encapsulant, and therefore improve the light extraction efficiency. In this paper, we prepared TiO<SUB>2</SUB>/silicone nanocomposites and studied the effects of the crystalline phases of TiO<SUB>2</SUB>, and the TiO<SUB>2</SUB> surface modifications on their optical properties. The rutile TiO<SUB>2</SUB> was found to be more effective to increase the RI of the nanocomposite than the anatase phase TiO<SUB>2</SUB>. At a 5 wt.% loading of TiO<SUB>2</SUB>, the RI was as high as 1.62 at the wavelength of 589 nm, which represents a significant improvement from 1.54 for silicone resin. In addition, surface modification was carried out using vinyl-terminated silane to improve the dispersion of nanoparticles in a silicone matrix, leading to a high relative transmittance of 84%. We also demonstrated that the optical property degradation of the nanocomposites in this paper was negligible after the accelerated reliability test.</P>

The Bric-a-brac, Tramtrack, Broad-complex (BTB) domain is a protein-protein interaction domain that is found in many zinc finger transcription factors. BTB containing proteins play important roles in a variety of cellular functions including regulation of transcription, regulation of the cytoskeleton, protein ubiquitination, angiogenesis, and apoptosis. Here, we report the cloning and characterization of a novel human gene, KLHL31, from a human embryonic heart cDNA library. The cDNA of KLHL31 is 5743 bp long, encoding a protein product of 634 amino acids containing a BTB domain. The protein is highly conserved across different species. Western blot analysis indicates that the KLHL31 protein is abundantly expressed in both embryonic skeletal and heart tissue. In COS-7 cells, KLHL31 proteins are localized to both the nucleus and the cytoplasm. In primary cultures of nascent mouse cardiomyocytes, the majority of endogenous KLHL31 proteins are localized to the cytoplasm. KLHL31 acts as a transcription repressor when fused to GAL4 DNA-binding domain and deletion analysis indicates that the BTB domain is the main region responsible for this repression. Overexpression of KLHL31 in COS-7 cells inhibits the transcriptional activities of both the TPA-response element (TRE) and serum response element (SRE). KLHL31 also significantly reduces JNK activation leading to decreased phosphorylation and protein levels of the JNK target c-Jun in both COS-7 and Hela cells. These results suggest that KLHL31 protein may act as a new transcriptional repressor in MAPK/JNK signaling pathway to regulate cellular functions.
